Refactor Parameterized and ParameterDescription class to improve separation of concern

[anonstudy]

This PR makes the following changes:

ParameterDescription.java

This PR refactors the addValue method by extracting the logic for handling collection type parameters into a separate method.

Changes:

• Created a new private method handleCollectionTypeParameter in the class
• Updated the addValue method to call handleCollectionTypeParameter where appropriate

Rationale:

• Single Responsibility Principle: The new method has a clear, single purpose of handling collection type parameters.
• Improved readability: Extracting this logic into a separate method makes the addValue method shorter and easier to understand.
• Easier maintenance: Changes to the collection type parameter handling can now be made in one place.

Parameterized.java

This PR refactors the parseArg method by extracting the field analysis logic into a separate method.

Changes:

• Created a new private method analyzeFields that encapsulates the field analysis logic
• Updated parseArg to call the new analyzeFields method where appropriate

Additionally, it refactors the parseArg method by extracting the method analysis logic into a separate method.

Changes:

• Created a new private method analyzeMethods that encapsulates the method analysis logic
• Updated parseArg to call the new analyzeMethods method where appropriate

Rationale:

• Improved separation of concerns: The parseArg method now focuses on high-level argument parsing, while field and method analysis are handled separately.
• Single Responsibility Principle: The new methods have a clear, single purpose of analyzing fields and methods.
• Enhanced readability: The parseArg method becomes more concise and easier to understand.
• Increased modularity: The two methods can now be modified or extended without affecting the rest of the parseArg logic.
• Potential for reuse: The extracted methods can be called from other parts of the codebase if field analysis is needed elsewhere.

Note:

• This refactoring does not alter the overall functionality; it reorganizes the existing code for better structure and maintainability.

Thank you for contributing to JCommander! :-)

This refactoring does neither solve any actual problem nor provides any actual benefit. It simply changes the code in a way you like it more, increasing complexity, purely driven by an academical view apparently. I do not see that it would be really beneficial for anybody to merge it, unless you actually proof that the new methods are of actual use anywhere in the code. So I kindly ask you to really use that new methods in other code locations to proof the benefit of your contribution. Thanks. 🤔
